Already bothered by a sore knee, Barry Bonds has bone chips in his swollen left elbow. He said he planned to continue playing with the problem until it forced him out.

Bonds was 0-for-2 with two walks, one intentional, in San Francisco's 2-1 victory over the Los Angeles Dodgers in a game delayed nearly two hours by rain. Ray Durham's sacrifice fly scored the go-ahead run in the ninth inning, helping the Giants win the series opener.

Bonds said the bone chips were discovered in spring training, causing him to miss a week. He told MLB.com before the game that he would continue playing until his arm 'blows up'.

Asked after Friday's game what he meant, Bonds said, 'It means I quit. Gone.'

However, he said he's 'not at all' worried about that happening.

'I played with bone chips before. I played with them in my knee with Pittsburgh many years,' he said. 'They only hurt when they're in the way. Once they move out of the way, you're all right.'

Still without a homer this season, Bonds said his arm was not the cause of his low offensive production.

'I don't make no excuses,' he said. 'It was me.'

Extra security guards were stationed between innings, the result of the Dodgers and major league baseball combining to tighten security around Bonds during the three-game series. A federal grand jury is reportedly investigating whether Bonds committed perjury when he testified in 2003 that he never used steroids.

Bonds said he had no reaction to the grand jury investigation.

'We just won a game. You got anything else to talk about?' he said. 'Does anybody want to talk about baseball?'

Fans stayed on Bonds' case, chanting 'steroids' while he stood in the outfield in the bottom of the first. In between batters, he glanced over his left shoulder at the seats behind him. In the bottom of the fifth, a small, unidentifiable object was tossed from the left field seats in Bonds' direction, but it didn't come near him.
